EPECIFICATION forming part of Letters Patent No. 338,317, dated March 23, 1886.

Appication filed November 27. 18: 5. Serial No. 184,075. (Specimens) To all whom it may concern.-

Be it known that I, ORLANDO M. THow- LESS, a subject of the Queen of Great Britain, residing at Newark, in the county of Essex and State of New Jersey, have invented a new and useful Alloy, of which the following is a specification.

The object of my invention is to produce an alloy having theappearance and general characteristics of silver, to be used in the place of silver in the construction of articles of tableware, watch-cases, and for other likepurposes. To attain this object I take the ordinary German silver of comnierce,which is composed of nickel, zinc, and copper in somewhat varying proportions. I prefer, however, in practice, to use the following proportions: nickel, eighteen parts; zinc, eighteen parts, and copper sixty-four parts. These ingredients are mixed together with a suitable flux and melted in a crucible. When fusion has taken place, pure silver is added in the proportion of seven parts of such silver to ten parts of the alloy.

Instead of adding the silver directly to the alloy, such alloy may be run off into pigs and the fusion with the silver subsequently efiected.

The proportion of the ingredients in the German-silver alloy may be varied somewhat without materially changing the character of the same, and the proportions of pure silver and the alloy may be varied also to suit par-
